fix(import): 3 production bugs — items cache, CUI lookup, ANAF name

1. SQLite order_items overwrite on re-import (VELA CAFE #484669620):
   add_order_items, save_orders_batch, mark_order_deleted_in_roa now use
   DELETE + INSERT so GoMag quantity changes propagate to dashboard.

2. PL/SQL strict CUI lookup tolerates whitespace (FG COFFE #485065210):
   cauta_partener_dupa_cod_fiscal regex ^RO\d → ^RO\s*\d; IN-set uses
   canonical v_ro_cui. Platitor/neplatitor business rule preserved.
   Python defensive: re.sub whitespace collapse in determine_partner_data.

3. New PJ partners use ANAF official denumire (denumire_override) instead
   of GoMag company_name. Existing partners (found by CUI) untouched.

Tests: 18 new (5 SQLite unit, 8 Python unit, 5 Oracle PL/SQL). All green
locally: 228 unit + 26 oracle + 33 e2e.
